4Chronic electrode implants — are electronic devices implanted into the brain. They may record electrical impulses in the brain or they may stimulate neurons with electrical impulses from an external source. Contents 1 Clinical applications and direction 1.1 Clinical… …
5Standard hydrogen electrode — NHE redirects here. For the sodium hydrogen exchanger protein, see Sodium hydrogen antiporter. The standard hydrogen electrode (abbreviated SHE), is a redox electrode which forms the basis of the thermodynamic scale of oxidation reduction… …
6Rotating ring-disk electrode — A rotating ring disk electrode (RRDE) [Albery W.J.; Hitchman M.L. Ring Disc Electrodes Oxford: Clarendon Press 1971 (ISBN 978 0198553496)] is double working electrode used in hydrodynamic voltammetry, very similar to a rotating disk electrode… …
7Rotating disk electrode — A rotating disk electrode (RDE) is a hydrodynamic working electrode used in a three electrode system. [Bard, A.J.; Faulkner, L.R. Electrochemical Methods: Fundamentals and Applications. New York: John Wiley Sons, 2nd Edition, 2000.] Structure The …
8Carbon paste electrode — A carbon paste electrode (CPE) is made from a mixture of conducting graphite powder and a pasting liquid. These electrodes are simple to make and offer an easily renewable surface for electron exchange.Carbon paste electrodes belong to a special… …
9oxygen-electrode-based sensor — Sensor in which an oxygen electrode, which measures the amount of oxygen in a solution, is coated with a biological material such as an enzyme which generates or absorbs oxygen when the appropriate substrate is present. When the biological… …
10History of the battery — could only function in a certain orientation. Many used glass jars to hold their components, which made them fragile. These practical flaws made them unsuitable for portable appliances. Near the end of the 19th century, the invention of dry cell… …
